<FioraAeterna> an interesting article for ya'll math folks: diffyq solvers can lie when you try to look for solutions where there… https://t.co/fxX8rKRuMB
<Fiora>
?
<egg>
Fiora: so tbh that's a fairly obvious thing: if you use fixed step on an ODE whose solution has a singularity (or just something stiff) you better know why you picked that step size; alternatively, adaptive step size is your friend
<Fiora>
what'sthe \o/
<Fiora>
for
<egg>
Fiora: being happy at hearing about numerical integration of ODEs? :-p
<Fiora>
ohh!
<egg>
Fiora: this reduce-step-size-makes-it-eggsplode thing means that adaptive stepsize will catch it instantly
<Fiora>
aha
<egg>
(it will try reducing the stepsize to 0)
<egg>
(at which point if you wrote your integrator correctly you catch that, otherwise you have an infinite loop :-p)
<Fiora>
there was actually a great thread on twitter the other day where @liasae was having graphical glitches with her lighting code on some platforms
<Fiora>
turns out the issue was quite numerical
<egg>
(ok to be fair I actually got two semesters of numerics at ETHZ, so I do have formal training in that stuff)
<Fiora>
see, that particular lighting function had an exponent of 220 for specular
<Fiora>
x^220
<egg>
Fiora: was that the thing with the goosey tolerances?
<egg>
Fiora: I had never heard those equations referred to anything but "differential equations" unabbreviated or "ODEs" resp. "PDEs", so I didn't know about the alternative spelling of diffyq :-p
<SnoopSiTh>
never seen that spelling but it's cute
SnoopSiTh is now known as SnoopJeDi
<SnoopJeDi>
So the several-month-long opera of "why the crap doesn't my simulation agree with the DIY Runge-Kutta tracker my supervisor wrote" is finally over
<egg>
(well okay I've heard them called Differentialgleichungen and gewöhnliche Differentialgleichung bzw. partielle Differentialgleichung but that's slightly different)
<SnoopJeDi>
The answer: he (unintentionally?) lied to me when he said the inputs he gave me were the same inputs he actually used
<SnoopJeDi>
The difference in the RF cavity is only at the ~1% level but that's more than enough to change the stable point of the longitudinal dynamics :(
<Fiora>
i've heard "diff eq"
<SnoopJeDi>
yea diff E.Q. is very common in American English
<Fiora>
ahhh
<egg>
Fiora: yeah, I generally have not at all been exposed to american idioms in math
<egg>
same with my question to bofh the other day about why people call finite fields "Galois"
<Fiora>
didn't know it was an american abbreviation
<Fiora>
wait. "in math"
<SnoopJeDi>
:O
<Fiora>
isn't "math" an american idiom???
<Fiora>
as opposed to maths
<Fiora>
or is maths the britishism
<egg>
Fiora: hm, good point
<SnoopJeDi>
maths predates by a lot AFAIK
<egg>
Fiora: in french it'd definitely be maths with an s
<egg>
I have picked up an americanism D:
<SnoopJeDi>
dunno if "diff eq" is idiomatically American or if it's that way in the UK/etc. too
<egg>
Fiora: note that "maths" in french would be pronounced [mat] of course, because we like having letters that we don't pronounce. But it still has an s :D
<SnoopJeDi>
I am in hindsight quite glad my German ODEs prof made a big stink about pronouncing Euler as "yoo-ler"
<Fiora>
i thought it was pronounced 'oiler'
<egg>
Fiora: it is
<SnoopJeDi>
I believe that's the proper Swiss pronunciation
<Fiora>
oic what you mean
<SnoopJeDi>
but it made me aware of the broad trend of "anglophone or gtfo"
<egg>
(the french say uh-lair because we're shit at pronouncing foreign languages)
<SnoopJeDi>
"your, uh, your name is really annoying. we're gonna call you Snellius. Actually, forget that. We'll call you Snell."
<Fiora>
ring ring ring ring ring ring ring, an anglophone
<egg>
?
<SnoopJeDi>
also c.f. Poincaré, Planck, Schrödinger, Legendre, ...
<egg>
... do I want to know how you pronounce those names
<SnoopJeDi>
no
<SnoopJeDi>
I mean, not typical American pronunciations
<egg>
let alone Lebesgue
<Fiora>
schurdinger, right?
<SnoopJeDi>
I make an effort to say things properly
<SnoopJeDi>
because it's literally the most basic level of intercultural respect :|
* e_14159
slaps Fiora with a medium-sized Forelle
<SnoopJeDi>
actually egg you might be able to answer a question I've had since The Imitation Game came out
<SnoopJeDi>
is "yooler" a common pronunciation in the UK?
<SnoopJeDi>
do you know if*
<egg>
I don't know, ask Iskierka?
<Fiora>
yooler is how people who haven't heard it prnounced correctly pronounce it by reflex
<Fiora>
i.e. it's the "obvious reading"
<SnoopJeDi>
it was one of several things that greatly aggravated me about the film but it occurred to me that perhaps it's common there too
<SnoopJeDi>
and even if it's not historical it's...by far not the most egregious re-writing of history that movie undertook
<egg>
(tbh in french we pronounce Gauss as you would [gos], because au is an [o] in french)
<SnoopJeDi>
huh, I always thought that one was a hyperforeignism
<egg>
I spent a bus trip talking to another student at ETHZ about something that was related to a result of Gauss, and at the end he asked me who the hell that was
<SnoopJeDi>
welp, another minor indiscretion :(
<egg>
(a french speaking Swiss student)
<egg>
(so who speaks french, hence why I was saying [gos], but pronounces Gauss correctly)
<SnoopJeDi>
OH, I see what you're saying
<egg>
Fiora: SnoopJeDi: and FYI, Lebesgue is [ləbɛɡ], please ignore most of those letters :-p
<SnoopJeDi>
I thought you were saying [gos] is correct and now I'm not really sure why I thought that. Exhaustion is catching up with me maybe
<SnoopJeDi>
egg, "Français: please ignore most of those letters"
<SnoopJeDi>
(not that I have any right to throw stones, speaking only a bastard tongue)
<egg>
extra letters, but still not enough to derive the pronunciation from the spelling :-p
<egg>
"les poules du couvent couvent"

SnoopJeDi: is there such a thing as a non-bastard tongue (or do you mean that we have William the Bastard to thank for the amount of French in English)
<SnoopJeDi>
I'm poking fun at English, but your point is well motivated
<SnoopJeDi>
(*clearly* conlangs are the solution!)
<UmbralRaptor>
egg: Sindarin and Quenyan would probably non-bastard tongues.

<UmbralRaptor>
Yeah, other things to do.

On a quasi-related note, have you gotten into many epics? (Illiad, Odyssey, Aenid, Beowulf, Gilgamesh, Ramayana)
<SnoopJeDi>
I have very warm memories of The Hobbit, though. Teacher read that to our class a bit at a time once upon an elementary
<SnoopJeDi>
UmbralRaptor, not past the highly diluted excerpt exposure one gets in public education :/
<SnoopJeDi>
I think I have a copy of The Odyssey on my bookshelf though, my ex discarded quite a lot of her books when she moved

speaking of which I should get back to reading the adventures of Pantagruel
<Fiora>
the odyssey is wonderful if solely for the part where odysseus dad jokes a cyclops
<egg>
UmbralRaptor: does Pantagruel count as an epic :-p
<SnoopJeDi>
Fiora++ worth the price of entry
<UmbralRaptor>
egg: I went through Lattimore translations of the Illiad and Odyssey some years ago.
<UmbralRaptor>
Fiora: I'm told that there's even more punnery in the origional Greek.
<UmbralRaptor>
egg: In terms of size, yes?
<egg>
UmbralRaptor: but what about in terms of content :-p
<SnoopJeDi>
I was discussing translation and puns with someone yesterday. Reading the English translations of Liu Cixin's trilogy you can get the sense that a lot of wordplay gets lost
<SnoopJeDi>
although as praise for the translators, doing enough to even make the reader aware they've missed something is excellent work!
